The device has a design which allows it to move without getting stuck on power cords and other stray objects.
This helps to prevent the device from entering a particular area. Signals transmitted from floor stands tell the device to stop when it reaches the edge of a room or a predetermined line.
The device sees an approaching obstacle, e.g. furniture or a vase, and slows down to prevent itself from bumping in it.
A gyroscope is a sensor that tracks the orientation of a device, more specifically by measuring the angular rotational velocity. Initially, they were built using a spinning rotor to detect changes in orientation, like twisting or rotation.
Allows you to program the device to begin at a convenient time.
A remote control allows you to control the device remotely. The remote control can be included or optional.
